Abstract

An equivalent circuit (EC) based analytical way is shown to optimize the discrete conductivity profile of PML-like Absorbing Boundary Conditions for layered media transmission line termination. for validation, a two cell microstrip transmission line (Substrate /spl epsiv//sub r/+12.9) absorber is presented with S/sub 11/<-60 dB in a 3D FDTD simulation, which is in excellent agreement with the Equivalent Circuit model´s prediction. Therefore a significant reduction of the ABC computation time can be achieved.
